“…There are currently two main types of dealing with cross-correlation interference in the field of external radiation source detection. The first type of method eliminate s all direct signals in the return channel [4], avoiding the appearance of cross-correlation interference, and the second [5]the direct signal in which the echo signal is detected to reduce the effect of inter-correlation interference [6][7][8].…”

The features of the external radiation source radar result in the target echo power often being relatively low, and for the echo signal, the cross-correlation interference of the direct satellite signal causes the target echo to be undetected. This paper proposes a Q-way coherent-noncoherent accumulation method to suppress the inter-correlation interference from the radiation source direct signal without reconstructing all the direct signal eliminations, greatly reducing the amount of computation, for the suppression of inter-correlation interference and the correct detection of echoes provides a new idea.
